  • the invention relates to a drive device with a manual transmission according to the preamble of patent claim 1.
  • Drive devices with a manual transmission and a drive machine designed, for example, as an internal combustion engine are generally known in vehicle construction.
  • the prime mover is operatively connected to a drive shaft, which in turn drives the input side ⁇ of a clutch assigned to the manual transmission.
  • the output of this clutch is then connected in terms of drive technology to the input shaft of the gearbox, the output of which acts on vehicle wheels to be driven, for example via a differential gear.
  • Such manual transmissions are usually designed as step transmissions, during their operation there is an interruption in the tractive force when changing gears, which also applies to the so-called automated step transmissions. This generally results in the requirement to keep the phases of the interruption of traction as short as possible in the sense of increased driving comfort.
  • the invention is therefore based on the object of designing a drive device with a manual transmission in such a way that the time period of the interruption in tractive force when changing gear is further minimized and the drop in tractive force is reduced.
  • the invention provides that a shift brake clutch is arranged in the power transmission path from the drive machine to the shift transmission between the drive shaft and the shift clutch, and that the output of the shift brake clutch can be brought into operative connection with the transmission output.
  • the engine speed is thereby reduced by the amount that results from the change in speed of the gear change, while at the same time supporting the torque on the transmission output.
  • the drive device according to the invention thus prevents both the complete slump in the transmission of tractive force that usually occurs in the drive devices according to the prior art, and significantly reduces the time span with reduced tractive force.
  • an otherwise conventional transmission brake as known for example from DE 19652 916 A1, can be omitted.
  • the support torque is received via a secondary shaft which can be driven by the shift brake clutch and which transmits this torque to the transmission output in a torque path preferably parallel to the shift transmission.
  • the location of the introduction of torque on this transmission output can be designed to be switchable in order to further increase the torque on the transmission output.
  • idler gears can preferably be assigned to the auxiliary shaft, which can be selectively and alternately connected to the transmission output by means of a coupling device.
  • It is a shift group is assigned to the manual transmission, for example in the form of a planetary gear stage.
  • the transmission output shaft directly associated with the manual transmission is in operative connection with the planetary gear stage, the output of which drives the cardan shafts of a vehicle equipped with this drive device in the form of a main output shaft, for example via a differential gear.
  • the output of the shift brake clutch is connected in a rotationally fixed manner to an idler gear which is rotatably mounted on the drive shaft.
  • This idler gear preferably meshes with an idler gear mounted on the gearbox housing, which is also meshed with a fixed gear on the auxiliary shaft.
  • the output of the auxiliary shaft is preferably assigned at least two idler gears, which are mounted on the latter and can be connected to the gearbox output alternatively and alternatively via a mechanical coupling device.
  • This coupling device is designed, for example, as a sliding sleeve.
  • the idler gear close to the gearbox meshes with another idler gear which meshes with a gearwheel fastened on the gearbox output shaft of the gearbox.
  • the idler gear remote from the gearbox meshes with an idler gear which meshes with a gearwheel attached to the main output shaft of the drive device.
  • Another development of the invention provides that the transmission output shaft of the manual transmission is operatively connected to the input of a Post-switching group, the output of which is formed by the main output shaft.
  • the intermediate gear which meshes with the gear attached to the main output shaft is a planet gear of a secondary stage designed as a planetary gear.
  • Fig. 1 is a schematic structural view of the drive device according to the invention.
  • FIG. 2 shows the qualitative course of various parameters of the drive train according to FIG. 1 over time.
  • a transmission output 5 also has a transmission output shaft 6 and a main output shaft 7.
  • a shift brake clutch 9 is arranged between the drive shaft 2 and the shift clutch 3, which also serves as a starting clutch, the drive shaft 2 being a radial drives the inner disk pack 10 of the shift brake clutch 9 permanently.
  • the drive shaft 2 is guided axially through the shift brake clutch 9 and acts permanently on an input-side clutch surface 11 of the shift clutch 3.
  • a radially outer disk set 12 of the switching brake clutch 9 is arranged in a rotationally fixed manner in a clutch housing 13, which drives a gearwheel 14 arranged coaxially to the drive shaft 2.
  • This gearwheel 14 is in engagement with an intermediate gear 15 which is supported on the housing 8 and which meshes with a drive gear 17 arranged in a rotationally fixed manner on a secondary shaft 16.
  • This auxiliary shaft 16 is rotatably supported in the housing 8.
  • auxiliary shaft 16 At the end of the auxiliary shaft 16 opposite the drive wheel 17, its output 18 is assigned to the gear output 5.
  • two idler gears 19, 20 are mounted on the auxiliary shaft 16.
  • a transmission group 22 Arranged between the transmission output shaft 6 and the main output shaft 7 is a transmission group 22 designed as a planetary gear stage.
  • the idler gear 19 arranged to the left of the coupling device 21 in this example engages in an idler gear 23, which in turn meshes with a gear 24 arranged on the transmission output shaft 6 in a rotationally fixed manner, while the other idler gear 20 is arranged on an idle gear 25 on the main output shaft 7 via an idler gear 25 Gear 26 is in mesh.
  • the intermediate gear 25 is preferably a planet gear of the planet gear stage.
  • the starting clutch 3 which overlaps with the opening shifting brake clutch 9, takes over the engine torque in such a way that, after the shifting process has been completed, the entire torque flow takes place bypassing the auxiliary shaft 16.
  • time profiles of some variables relevant to the drive device are shown relative to one another in FIG. 2.
  • the time t is plotted on the horizontal axes, the times t1 and t2 respectively representing the beginning and the end of a mechanical gear change process.
  • the curve of the torque guided via the clutch 3 is initially shown with a curve 30 and the corresponding torque via the clutch 9 with a curve 32.
  • the overlap phase of the two clutches 3, 9 lying between t1 and t2 is clearly visible.
  • the curve 34 shown above in FIG. 2 represents the course of the tractive force, while the curve 36 shows the course of the engine torque.
  • Curves 38 and 40 represent the course of the engine speed and the gearbox speed in the event of an upshift, the course of curve 40 being drawn in dashed lines. These two curves 38, 40 differ from one another only in the time interval between the times t1 and t2. It can be clearly seen from the course of the curve 34 that the overlapping of the torque profiles 30 and 32 reduces the tensile force, but advantageously does not completely collapse.

Abstract

L'invention concerne un dispositif d'entraînement doté d'une boîte de vitesses (4), d'un moteur et d'un embrayage (3). L'invention vise à réduire la phase d'interruption de force de traction lors d'un passage de vitesse. A cet effet, le dispositif d'entraînement est équipé d'un demi-accouplement d'embrayage (9) monté entre le moteur et l'embrayage de séparation (3) de sorte que, lors d'un passage de vitesse, les processus d'ouverture et de fermeture superposés des deux embrayages (3 et 9) servent de support au couple du moteur sur une sortie de boîte (5).
